First we do 40 + 5 = 45
Second we do 45 – 32 = 13
Third we get 13/18 which is the answer..
The order of operation is:
1. parentheses
2. exponents
3. multiply
4. divide
5. addition
6. subtraction
Remember the word pemdas. The first letter of each operation.

it is evaluated in the following order : first you evaluate the brackets, then the division, then the multiplication, then the addition and in the last the subtraction.
[(40 + 5) 32] / 9 * 2
[45 32] / 9 * 2
13 / 9 * 2
1.4 * 2
2.8 (approx.)

{(40 + 5) – 32} / 9 * 2 =
{(45) – 32} / 9 * 2 =
(13) / 9 * 2 =
13 / 18.

Follow order of operations:
Do these steps from left to right
PEMDAS is a good acronym for it
Parantheses (and brackets)
Exponents
Multiplication
Division
Addition
Subtraction

solve the inner brackets first
[(45)32]/9×2
=[4532]/9×2
=13/9×2
=26/9
=2.8/9
